  abstract = {{N}on-calcifying photosynthetic anthozoans have emerged as a group that may thrive under high carbon dioxide partial pressure (p{CO}(2)) conditions via increased productivity. {H}owever, the physiological mechanisms underlying this potential success are unclear. {H}ere we investigated the impact of high p{CO}(2) on the dissolved inorganic carbon ({DIC}) use in the temperate sea anemone {A}nemonia viridis. {W}e assessed the impacts of long-term exposure to high p{CO}(2), i.e. sampling in situ natural {CO}2 vents ({V}ulcano, {I}taly), and short-term exposure, i.e. during a 3 wk controlled laboratory experiment. {W}e focused on photo-physiological parameters (net photosynthesis rates, chlorophyll a content and {S}ymbiodinium density) and on carbonic anhydrase ({CA}) activity, an enzyme involved in the energy-demanding process of {DIC} absorption. {L}ong-term exposure to high p{CO}(2) had no impact on {S}ymbiodinium density and chlorophyll a content. {I}n contrst, short-term exposure to high p{CO}(2) induced a significant reduction in {S}ymbiodinium density, which together with unchanged net photosynthesis resulted in the increase of {S}ymbiodinium productivity per cell. {F}inally, in both in situ long-term and laboratory short-term exposure to high p{CO}(2), we observed a significant decrease in the {CA} activity of sea anemones, suggesting a change in {DIC} use (i.e. from an {HCO}3- to a {CO}2 user). {T}his change could enable a shift in the energy budget that may increase the ability of non-calcifying photosynthetic anthozoans to cope with ocean acidification.},
